S-90031A148 Length 1/2" Wood Screws

Key Features & Benefits at a Glance

• Enhanced corrosion resistance with zinc-plated steel construction for reliable performance in various woodworking environments
• Superior thread grip and reduced splitting through thread forming design that displaces material instead of cutting it
• Clean, flush installation with 82° countersink angle and flat head profile for professional finishing
• Secure drive engagement with Phillips No. 2 drive system preventing cam-out during installation
• Optimized wood holding power with partial threading that concentrates grip where needed most
• Versatile material compatibility with specific drill bit recommendations for both hardwood and softwood applications
• Regulatory compliance assurance meeting RoHS 3 and REACH standards for safe industrial use

Professional Applications & Engineering Value

These No. 6 x 1/2" wood screws are engineered to address common fastening challenges in wood applications. The zinc-plated steel construction provides essential corrosion protection for interior wood projects, while the thread forming design creates stronger, more reliable connections by compressing wood fibers rather than cutting them, significantly reducing the risk of material splitting. The Phillips flat head configuration with standard 82° countersink angle ensures seamless flush mounting in furniture assembly, cabinetry, and general wood construction. The partially threaded shank design concentrates gripping power in the engagement zone while allowing for easier alignment and reduced installation torque. These wood screws deliver consistent performance across both hardwood and softwood substrates, with precise drill bit size recommendations provided for optimal pilot hole preparation.

Specification Summary & Compliance

These inch-system fasteners feature a 0.138" thread diameter with approximately 18 threads per inch and minimum thread length of 0.333". The thread forming tapping method creates secure connections without chip removal, while the right-hand thread direction follows standard installation practices. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and restricted substance compliance for industrial applications. The flat head profile maintains standard dimensions with 0.279" head diameter and 0.083" head height for consistent countersinking performance.
